Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and particularly to an air conditioner. Background Art

[0002] With the increasing improvement of people's living standards, air conditioners have become an indispensable household appliance at home. Currently, air conditioners are usually provided with rotatable air deflector plates, and a drive box is used to drive the air deflector plate to rotate so as to direct the air flow blown out by the air conditioner, thereby realizing the function of adjusting the air direction. The current drive boxes are generally directly installed on the middle frame and are exposed indoors, with relatively low aesthetic appearance. Moreover, since the drive box will vibrate or be impacted during the driving process, the drive box may shift relative to the middle frame during operation, resulting in poor stability and affecting the air guiding effect. Summary of the Invention

[0003] The problem solved by the present invention is how to prevent the drive box from shifting relative to the middle frame, ensure the stability of the drive box during operation, enhance the air guiding effect, and achieve the shielding of the drive box to improve the aesthetic appearance.

[0004] To solve the above problems, the technical solution of the present invention is realized as follows:

Detailed implementation manners

[0024] To make the above - mentioned objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific embodiments of the present invention will be given with reference to the accompanying drawings.

[0025] Please refer to Figures 1 to 7 , the embodiment of the present invention provides an air conditioner 100 for regulating the indoor temperature. It can prevent the drive box 130 from displacing relative to the middle frame 110, ensure the stability of the operation of the drive box 130, enhance the air - guiding effect, and achieve the shielding of the drive box 130 to improve the aesthetics.

[0026] It should be noted that the air conditioner 100 is a wall-mounted air conditioner, which is hung on the wall and can blow hot air or cold air into the room to achieve the functions of heating or cooling.

[0027] The air conditioner 100 includes a middle frame 110, a cover plate 120, a drive box 130, a wind deflector 140, a blower (not shown in the figure) and a heat exchanger (not shown in the figure). Among them, the drive box 130, the wind deflector 140, the blower and the heat exchanger are all installed in the middle frame 110. The blower is used to generate negative pressure to drive the air flow and form an outlet air flow. The heat exchanger is used to exchange heat with the outlet air flow so that the outlet air flow has the function of heating or cooling. Specifically, the drive box 130 is connected to the wind deflector 140. The drive box 130 is used to drive the wind deflector 140 to rotate. The wind deflector 140 is used to guide the outlet air flow to achieve the function of adjusting the wind direction. The cover plate 120 is covered outside the drive box 130 and is detachably connected to the middle frame 110 to achieve the shielding and protection of the drive box 130 and improve the aesthetic appearance of the air conditioner 100.

[0028] The middle frame 110 includes an end plate 111, a connecting plate 112 and a limiting plate 113. The end plate 111 and the limiting plate 113 are arranged at intervals and are both connected to the connecting plate 112. In this embodiment, the end plate 111, the connecting plate 112 and the limiting plate 113 are integrally formed to improve the connection strength. Specifically, the drive box 130 is installed on the end plate 111 and abuts against the limiting plate 113. The wind deflector 140 is rotatably installed on the side of the limiting plate 113 away from the end plate 111. The limiting plate 113 is provided with a through hole 1131. The drive box 130 can pass through the through hole 1131 and is connected to the wind deflector 140 to achieve the function of driving the wind deflector 140 to rotate.

[0029] Furthermore, the cover plate 120 is covered outside the drive box 130. The cover plate 120 is used to shield and protect the drive box 130 and improve the aesthetic appearance. The cover plate 120 is detachably connected to the connecting plate 112. The connecting plate 112 can limit and fix the cover plate 120 to facilitate the installation and disassembly of the cover plate 120, thereby facilitating the maintenance and repair of the drive box 130. Specifically, the cover plate 120 is provided with a retaining block 121. The retaining block 121 abuts against one end of the drive box 130 away from the limiting plate 113, that is, the drive box 130 is clamped between the retaining block 121 and the limiting plate 113. The retaining block 121 and the limiting plate 113 act together to clamp the drive box 130 to prevent the drive box 130 from displacing relative to the middle frame 110 in the event of vibration or impact, ensuring the stability of the operation of the drive box 130 and enhancing the air guiding effect.

[0030] It should be noted that the connecting plate 112 is provided with a reinforcing rib 1121. The reinforcing rib 1121 and the limiting plate 113 are arranged at intervals, and a stop portion 1122 is extendedly arranged on the reinforcing rib 1121. The limiting plate 113 is provided with a limiting portion 1132, and the through hole 1131 is opened in the limiting portion 1132. The stop portion 1122 and the limiting portion 1132 are arranged oppositely and jointly form an assembly cavity 150 for installing the driving box 130. Specifically, the anti-return block 121 and the driving box 130 are both arranged in the assembly cavity 150. One end of the driving box 130 abuts against the limiting portion 1132, and the other end abuts against the anti-return block 121. The limiting portion 1132 and the anti-return block 121 jointly act to limit the driving box 130 and prevent the driving box 130 from displacing relative to the middle frame 110.

[0031] In this embodiment, the anti-return block 121 is clamped between the driving box 130 and the stop portion 1122, that is, one end of the anti-return block 121 abuts against the driving box 130, and the other end abuts against the stop portion 1122. The stop portion 1122 can apply a abutting force to the driving box 130 through the anti-return block 121 to press the driving box 130 against the limiting portion 1132, further improving the limiting effect on the driving box 130. Specifically, when the installation of the driving box 130 is completed and the cover plate 120 is covered outside the driving box 130, the anti-return block 121 of the cover plate 120 is clamped between the driving box 130 and the stop portion 1122. At this time, the stop portion 1122, the anti-return block 121, the driving box 130 and the limiting portion 1132 are sequentially arranged in abutment. The stop portion 1122 and the limiting portion 1132 jointly act to clamp the anti-return block 121 and the driving box 130 to prevent the anti-return block 121 and the driving box 130 from displacing and ensure the limiting effect.

[0032] The anti-return block 121 includes a block body 1211, a first abutting rib 1212 and a second abutting rib 1213. The first abutting rib 1212 and the second abutting rib 1213 are oppositely arranged on both sides of the block body 1211 and are both connected to the block body 1211. The first abutting rib 1212 abuts against the driving box 130, and the second abutting rib 1213 abuts against the stop portion 1122. Specifically, one side of the block body 1211 abuts against the driving box 130 through the first abutting rib 1212, and the other side abuts against the stop portion 1122 through the second abutting rib 1213. By adopting the way of line-surface cooperation (the first abutting rib 1212 abuts against the driving box 130 and the second abutting rib 1213 abuts against the stop portion 1122), compared with surface-surface cooperation, the cooperation precision can be improved, the smoothness and reliability during the cooperation process can be ensured, and the labor-saving effect can be achieved.

[0033] In this embodiment, both the first abutting rib 1212 and the second abutting rib 1213 are connected to the cover plate 120 to improve the connection strength between the cover plate 120 and the block body 1211, playing a strengthening role. Specifically, both ends of the first abutting rib 1212 are chamfered, and both ends of the second abutting rib 1213 are chamfered to play a role in guiding and sliding, facilitating the smooth sliding of the anti-return block 121 between the driving box 130 and the stopping portion 1122 during the covering process of the cover plate 120, and further achieving the effect of labor saving.

[0034] In this embodiment, the number of both the first abutting rib 1212 and the second abutting rib 1213 is two.
